The PXE boot loader is part of the BIOS and runs over the management interface of hardware platforms that are running Cisco IOS XR Software only. The vulnerability exists because internal commands that are issued when the PXE network boot process is loading a software image are not properly verified. An attacker could exploit this vulnerability by compromising the PXE boot server and replacing a valid software image with a malicious one. Alternatively, the attacker could impersonate the PXE boot server and send a PXE boot reply with a malicious file. A successful exploit could allow the attacker to execute unsigned code on the affected device. Note: To fix this vulnerability, both the Cisco IOS XR Software and the BIOS must be upgraded. The BIOS code is included in Cisco IOS XR Software but might require additional installation steps. For further information, see the Fixed Software section of this advisory."},{"lang":"es","value":"Una vulnerabilidad en el cargador de arranque mejorado Preboot eXecution Environment (PXE) para Cisco IOS XR 64-bit Software, podría permitir a un atacante remoto no autenticado ejecutar código sin firmar durante el proceso de arranque de PXE en un dispositivo afectado. El cargador de arranque PXE es parte del BIOS y se ejecuta en la interfaz de administración de las plataformas de hardware que se ejecutan en Cisco IOS XR Software únicamente. La vulnerabilidad se presenta porque los comandos internos que son emitidos cuando el proceso de inicio de red de PXE está cargando una imagen de software no es verificada apropiadamente. Un atacante podría explotar esta vulnerabilidad al comprometer el servidor de arranque PXE y reemplazando una imagen de software válida por una maliciosa. Alternativamente, el atacante podría hacerse pasar por el servidor de arranque PXE y enviar una respuesta de arranque PXE con un archivo malicioso. Una explotación con éxito podría permitir al atacante ejecutar código sin firmar en el dispositivo afectado. Nota: Para corregir esta vulnerabilidad, tanto el  Cisco IOS XR Software como el BIOS deben ser actualizados. El código del BIOS está incluido en el Cisco IOS XR Software, pero puede requerir pasos de instalación adicionales. Para obtener más
